Hi Nathan,

OK, so this makes the problem more precise:

On Ubuntu 16.04 renaming the files makes Konqueror see them as octet-stream.
On openSuSE 13.1 the same does not.

I have checked on Raspbian and MX15 (both with TDE): without extension ogg and 
midi files become "unknown". Clicking on them opens teh "open with" dialog.

Text files, PDF and jpg open as if they had an extension.

SO your issue seems Ubuntu + TDE related.

Now we need someone with more understanding than me of what Konqueror uses to 
identify a file type to sort this out.
